From aad9ff97ddd774f03f5e055ade2b2d27a9c82ddb Mon Sep 17 00:00:00 2001 From: "Michael J. Ruhl" Date: Sun, 9 Apr 2017 10:15:57 -0700 Subject: IB/rdmavt/hfi1/qib: Use the MGID and MLID for multicast addressing The Infiniband spec defines "A multicast address is defined by a MGID and a MLID" (section 10.5). The current code only uses the MGID for identifying multicast groups. Update the driver to be compliant with this definition.
